ABSTRACT A new black fly species, Simulium (Comphostilbia) langkawiense, is described based on adult female, adult male, pupal, and larval specimens collected from Langkawi Island, Malaysia. This new species is similar in the configuration of the pupal gill to Simulium (Comphostilbia) gombakense Takaoka & Davies, 1995, originally described from Peninsular Malaysia, but differs from the latter species by the female genital fork with an anterolaterally angulated plate on each arm, the female tarsal claw tooth shorter than one half of the claw, the small number of male upper-eye large facets, the ventral plate with its ventral margin nearly flat in the middle when viewed posteriorly, and the inflated structure of the pupal gill with a less produced middle portion (width of middle inflated portion: length of inflated structure = 0.24). Taxonomic notes are also given to separate this new species from two other related species from Nepal and India. This represents another example of a unique species of black fly on one of the continental islands of Peninsular Malaysia.
摘要 本文基于从马来西亚兰卡威岛采集的成雌、成雄、蛹和幼虫标本，描述了一种新的黑蝇种类，即 Simulium (Comphostilbia) langkawiense。该新种与最初描述于马来半岛的 Simulium (Comphostilbia) gombakense Takaoka & Davies, 1995 在蛹期的翅瓣结构上相似，但与后者在以下几方面存在差异：雌虫生殖器叉的每支臂具前外侧角状片；雌虫跗爪齿小于爪长的一半；雄虫上眼小眼面数量较少；后观时，腹侧板中部的腹缘几乎是平的；蛹期的膨胀结构中中间部分不发达（中间膨胀部分的宽度：膨胀结构的长度=0.24）。文中还给出了分类学注释，以将该新种与来自尼泊尔和印度的两个相关种相区分。这是马来半岛大陆岛屿上独特黑蝇种的又一个例子。
